Gwyneth Paltrow relaunched the website for her Goop newsletter on Friday, and with the site's makeover came a new addition: The Goop collection.

Each week, according to the site, Goop will debut an exclusive, limited-edition collaboration, featuring clothing, home decor, or beauty products. First up? The Goop tee, done in partnership with Kain Label. The simple white t-shirt features black grosgrain piping on the shoulder and sides, inspired by tuxedo tailoring, and retails for $90. "We like to wear ours untucked," Paltrow suggests.
